Like reference numerals designate like parts throughout the several views. Figures 2, 3 and 5 are general figures which are drawn to a smaller scale than Figures 6 to 12 inclusive, the latter being intended to give a clearer illustration of the constructional details of the several devices comprised in the machine for automatically making the finishing welts.

As above set forth, this machine is specially utilizable for continuously and automatically making joint-covering welts or flexible headings such as those shown in Figures 1 and 4, with a minimum of labor. However the machine may be used for making other kinds of finishing welts, also supple fillers for rigid moldings.

The joint-covering welt or flexible beading shown in Figure 1 is made up of a core strip A carrying tacks P at suitable intervals, a corecovering strip B bent over the edges of said core strip A and cemented thereto, and a pliant facing strip C (made of natural leather or artificial leather for instance) cemented to said covering strip. The cement used for binding the three strips together may be rubber latex or the like.

As shown in Figure 2, the core strip A through which the tacks P have been previously set (in another machine which forms no part of the present invention and does not require therefore to be described or represented) is fed, tacks pointing upwards, by a guiding tube to a cement-applying device comprising a trough 2 filled with a suitable cement, for instance rubber latex as aforesaid. The function of this device is to lay the cement on the surface of the core strip A except over about one third of that face from which the tacks P project.

To that effect (see Figure 6) the core strip A is guided through a slotted block 3 screwed to the top of the trough 2 and travels on a curved sole l along which it is held by spaced upstanding plates 5 carried by a table 6 through which columns 1 are engaged, springs 8 being coiled around said columns and abutted between the table 6 and a cross head 9 through which a threaded spindle i8 is engaged. A knurled nut H may be screwed up or down on the spindle ill to permit adjustment of the pressure exerted by the springs 8 on the table 5 and consequently by the plates 5 on the core strip A while it travels along the curved sole 4. The upper level of the liquid cement (not shown) contained in the trough 2 must be such as to prevent said cement from entering the space between the plates 5 so that the middle portion of said strip A on both sides of the tacks P should remain devoid of cement. The constancy of the level of the cement in the trough 2 is ensured by an overflow device, as described hereafter. V

I The trough 2, which is adapted to furnish the cement or glue to the core strip element A, receives the cement through a pipe l2 (see Fig. 2) which extends downwardly from an overhead supply reservoir l3 having a removable cover M. The reservoir i3 is supported at the upper end of one of the main upright plates l5 of the machine frame. The trough 2 is removably carried on guiding L-shaped rail sections l6, l6 (see Figure 6) through the medium of a cross slide l1, said rail sections being secured in any approved way, for instance by grub screws, to the outer face of the upright frame plate IS. A bolt having a knurled head I B has its stem in engagement with the cross slide H; the stem of this bolt passes through a transverse clamping bar l'la the ends [1b of which bear against the rail sections l6, It. By screwing up the bolt head [8, the cross slide I1 is drawn outwardly by the bolt stem and the ends of said slide are pressed against the countersunk faces of the rail sections l6, is while the cross bar Ila is pressed simultaneously against the adjacent (outer) face of said cross slide H. The clamping of the trough 2 is thus performed.

Adjustment of the position of the cross slide I1 and trough 2 heightwise is thus rendered possible by loosening the bolt 18 when required and tightening it again after having shifted the cross slide I! up or down the rail sections IS, IS. A pair of bolts. H! (see Fig. 2) mounted in a way substantially similar to the bolts 8 engage cross slides spanning the rail sections I6, l6 and forming resting surfaces for the bottom of the trough 2 so as to assist in holding it up.

Through the cover I 4 of the reservoir I3 is screwed a threaded rod I4 fitted at its upper end with a knob I4 and at its lower end with a tapering valve ld' which can bear on a tapering seat l2 formed in the nipple uniting the top of the pipe l2 to the bottom of the reservoir l3 (see Fig. 2).

Adjustment of the rod I4 by means of the knob It" permits to regulate the flow of the liquid cement from the reservoir l3 to the pipe by varying the distance of the valve M' and seat l2.

The overflow of liquid cement from the uppermost trough 2 flows through any one of the depending pipes 20 which may project to the required height into said trough and which lead to another trough 2! connected by depenchng pipes 22 to a third trough 23 which in turn is connected by depending pipes 24 'to a bin 25 receiving the surplus cement. The troughs 2! and 23 are refnovably'carried by rail sections 25 secured to the frame upright plate l5 and held by bolts such as 2'! as aforesaid. The several troughs and interconnecting pipes can thus be removed bodily from the machine frame after having loosened the trough-holding slides and bolts, as above set forth, for instance for cleaning said troughs or for adjusting them to other positions.

When coming out of the cement-applying trough 2, the core strip A provided with tacks P and now having cement on a portion of its peripheral face passes over a doctor block 28 (see Fig. 6) by which any excess of cement is wiped off The core strip A then passes through a tubular channel 28 (see Fig. 2) to the heating and drying chamber provided inside the machine frame which forms an elongated chest. The atmosphere of the'heating and drying chamber 30 is kept at any suitable temperature by any heating plant, for instance by a piping 3| connected to the outlet of a fan 32 the inlet of which is connected to an air heater located outside the machine. This air heater forms no part of the invention and is not therefore illustrated. It may also in certain cases be located inside the machine, for instance in the form of a gas burner. Wide shutters 33 carried by hinges 34 maybe rocked up or down to permit an easy access to the interior of the heating chamber 30. Inside the latter are rotatably mounted flanged pulleys 35, 36 on which the core strip A having tacks P projecting outwardly is guided twice to be subjected to a drying operation due to the temperature of the surrounding atmosphere.- After passing on the pulley 35, tacks P pointing upwards, the core strip A passes around the pulley 36, then travels back towards the pulley 35, tacks P pointing downwards, and back again towards the pulley 36, tacks P pointing upwards. When leaving the pulley 36, for the second time, the core strip A is desiccated and its tacks P point downwards. During its travel to a jockey roller 31 carried by. a bracket 38 secured to the frame upright plate I5, the core strip A is twisted upon itself at T (without extraneous means) so as to cause its tacks P to point upwards as it reaches the jockey roller 31. Such twisting of the core strip A is initiated by the worker when starting the machine into operation and when engaging said core strip A on the jockey roller 31 for the first time. The twisting of the core strip A is afterwards preserved automatically.

While the core strip A travels along the above described circuit, another strip, tape or ribbon B which,.in the finished welt, will form the core covering or intermediate element of said welt travels along a different circuit which will now be described. The circuit of the strip B is similarly adapted to permit liquid cement or glue to be applied on it and then to become partly dried, whereafter the strip B must be juxtaposed to the core strip A. The strip Bis fed from a stock spool 39 revolubly carried by the frame upright plate I 5 and passes through the cement-contain ing trough 23 to receive therein a film of cement. After leaving the trough 23, the strip B enters the heating and drying chamber 30 and is guided over flanged pulleys 40, 4|. The pulley 4| is located adjacent the pulley 36 over which the core strip A is guided so that when they both leave the drying chamber 30, both strips A and B can be guided easily through the bracket 38 on their way to a dragging and assembling device which will now be described in detail with reference to Figure 7.

The device for dragging and assembling the strips A and B to form a partly finished welt is supported removably against the frame upright plate l5 of the machine by a pair of spaced guiding L-shaped rail sections 42, 42 bridged by a cross slide 43 which carries a bracket 45 to which are suspended certain of the operative parts of the device. A bolt having a knurled head 44 has its stem in engagement with the cross slide 43;

the stern of this bolt passes through a transverse clamping bar 43a the ends 4312 of which bear against the rail sections 42, 42. The co-operation of the parts 43, 43a, 44 is similar to the co-operation of the parts Ila, |8 as above-described.

Thus the position of the cross slide 43 is adjustable along the rail sections 42, 42.

, A pair of upright plates 46 (Fig. 7) are slightly spaced to provide a gap through which the tacks P set in the core strip A can freely pass as said strip is fed through the assembling device. A further cross slide 41 spannin the rail sections 42, 42 is adjustable as above-described by means of a bolt having a knurled head 48 whose stem passes through a clamping bar 41a. The cross slide 41 carries a bracket 49 which is provided on its upper face with two rows of vertical rollers 50 revolubly supported on pins set in girders 50a having tenons 50b fitted adjustably in mortises 500 formed in the upper face of the bracket 49, whereby said girders may be moved towards or away from each other and the distance between the rollers 50 can be adjusted to suit the width of the strip B. The latter is guided between the two rows of vertical rollers 50 by having its edges in frictional engagement with said rollers. The upright plates 46 and rollers 50 co-operate to properly locate the strips A and B relative to each other.

Just as they leave the plates 46 and rollers 50, the strips A and B which are now juxtaposed pass between a pair of assembling wheels 5|, 52 carried by horizontal axes supported by an upstanding plate 53 secured to the frame upright plate I5. The upper wheel 5| has a narrow groove 54 through which the tacks P of the core strip A can pass freely. The lower wheel 52 has a wide groove of such a cross sectional curved outline as to properly shape the strip B by bending its marginal portions over the edges'of the core strip A. To that effect, the width of the rim of the upper wheel 5| is such as to permit said wheel to engage the groove in the lower wheel 52 so that the two rims of said wheels may cooperate to perform the assembling operation.

The wheels 5| and 52 are removably held on their horizontal axes by nuts 5|a and 52a so that they may be taken off when required. This permits to substitute other wheels having rims of different size and shape in order to shape other strips, when a welt somewhat different in size from the one shown in Figure 1 has to be produced.

The shaping and assembling wheels 5|, 52

' may be driven in any approved way, for instance by a bevel gear actuated from a prime mover such as the electric motor 56 located in the machine frame. This drive is not illustrated as it 'may be of a conventional nature that anyone skilled in the art will understand and which forms no part of the invention. A castellated wheel is provided for vertically adjusting the position of the shaping wheel 5| with respect to the companion shaping wheel 52. The wheel 55 may be mounted for instance on a shaft actuating a worm wheel located inside the machine frame, the worm associated with said worm wheel engaging a bearing block carrying the stud of the shaping wheel 5|, said stud passing through an elongated opening of the upright frame plate l5. Said stud carries a cog wheel meshing with another cog wheel carried by the stud of the lower shaping wheel 52. In view of this construction, rotation of the castellated wheel 55 in the one or the other direction acts, through the worm gear, to slightly move the meshing cog wheels toward or away from each other, for instance vice can be easily understood from this explanation without requiring an illustration.

When coming out of the first assembling device which has just been described, the partly finished welt A-B passes through a supportingyoke '51 secured to the uprightframe plate lb of the machine. On a roller 58 carried by the yoke 51 is guided a strip C adapted to constitute the facing of the finished welt. The strip C is fed by a stock spool 59 revolubly supported by the upright frame plate l5; it passes over a tensioning roller 60, passes through the cement-applying trough 2| and travels through the heating and drying chamber 30' over a pulley 6|.

After having passed through the yoke 51, the strips A, Band C of the welt in the course of fabrication reach a second assembling device which is shown in detail in Figure 8. This device isremovably supported against the upright frame plate If by a pair of rail sections 62, 62 by means ofa cross slide 63 carrying a bracket 61. A bolt having a knurled head 64 has its stem in engagement with a clamping bar 630. the ends 53b of which bear on the outer faces of the rail sections 62,62; Adjustment is effected as above described. A channel member 66 is carried by the cross slide 63 and gives passage to the strips A, B, C while correctly positioning them with respect to one another due toits shape, as shown. From the bracket 61 depend a pair of cheek plates 68, 68 between which the tacks P set in the core strip A can freely pass. When coming out of this shaping device, the strips A, B, C are finally assembled by passing through a block 69 having a groove 19 through which the tacks P can. pass freely. Immediately beyond the block 69 are positioned a pair of superimposed shaping wheels ll, 12 supported by a plate 13 carried by the upright frame plate l5. The operation and adjustment of the shaping wheels I I, 12 are similar 'to those of the shaping wheels 5|, 52 described with reference to Figure 7 and need not be further described. The upper shaping wheel II has a groove Hi through which thetacks P can pass freely. A castellated wheel 15 permits the position of the upper shaping wheel H to be adjusted at will, as above described.

When coming out of the shaping wheels-ll, 12, as shown by the arrow f, the finished welt is ready made and has the structure shown in cross section in Figure 1. Such a welt can be used without further manipulation. It can be wound on a stocking pulley or drum (not shown) or other- I ner face of the wrapping strip E for preventing the welt when finished to become torn ofi right through. The threadsor strands F may beagglutinated together by any suitable adhesive such.

for instance as a solution of rubber latex.

The operative devices comprised in the machine which. are suitable for making a welt as shown in Figure} can be mounted on its upright frameplate 15a located on the side opposite to the one'occupiedlby the plate 15. This arrangement permits a welt such as the one shown in Figure 1 to be continuously manufactured on the one-side of the machine while a welt such as the one shown in Figure 4 is continuously manufactured on the opposite side. The devices carried to that effect by the upright plate [5a will now be described in detail with reference to Figure 5.

These devices comprise a plurality of dragging, cement-applying, shaping and assembling devices adapted to shape the strip E and to position the cord D and strip F of which the welt is to be made. Said devices are so constructed as to lend themselves to mounting either on the plate l5 or on the plate l5a of the machine frame. Thus shaping devices adapted to make a welt as shown in Figure 1 may be mounted both on the frame plate I5 and on the frame plate We to permit a larger output of such welt. Conversely, shaping devices adapted to make a welt as shown in Fig ure 4 may be mounted on both frame plates l5 and [lid to permit a larger output of said welt. Said shaping devices may also be used with slight appropriations for continuously and automatically making other kinds of welts also made up of a plurality of strips or bands assembled and cemented together.

Standard supporting and guiding means as above described are provided on both upright frame plates of the machine frame for permitting the shaping and assembling devices to be mount- 3 comb 80, such threads or strands reach a cement containing trough 2a .fed by a tube [2a depending from a cement reservoir liia provided with a removable cover lea. This reservoir l3a. is constructed as the reservoir l3 and it comprises similarly a valve operated through a rod (notshown) by a knob Ha". This construction does not require to be again described here.

Before entering the trough 2a, the threads F pass over a guide 8|. When leaving said trough,

the threads pass under a small doctor blade 82 which wipes off any excess of liquid cement and only leaves on said threads a thin film of cement (for instance a solution of rubber latex) whereafter the lap of threads enters the heating and drying chamber 30. This chamber is closed on the side of the machine shown in Figure 5a by pivotable shutters 33a carried by hinges 3%.

The threads or strands F coated with cement pass over a guiding pulley 83 revolubly mounted in the drying chamber and then through a proshaping device 84 located adjacent said chamber.

The pre-shaping device 8d is shown in detail in Figure 9. It comprises a bracket 85 having a slot 8% through which the lap of threads F passes. The bracket 85 is carried by a cross slide 81 received between L-shaped rail sections 89 secured to the upright frame plate I5a of the machine.

A bolt having a knurled head 38 has its stem engaged with the cross slide 8'! and through a clamping bar 81a the ends 87b of which bear against the rail sections 89. Loosening and tightening up of the bolt 88 permits to adjust the position of the=cross slide 81 along the rail sections 89, 8Q in order to vary the height of the device 84 above the ground. The lower portion of the slot 86 must be so shaped as to permit passage of the cord D which maybe fed from any convenient source, for instance from a stock spool (not shown). The cord D is guided on its way to the lower portion of the slot 86 by a grooved roller 90 carried by the bracket 85 and by a grooved slideway 9|. The lower part of the bracket 85 is formed moreover with a transverse slot 92 through which passes the strip E which, as above described, will form the wrapping of the welt when finished.

The strip E, is fed from a spool 39a revolubly mounted on the upright frame plate a of the machine. Said strip passes through a cementapplying trough 23a between apair of rollers 93, 94. The quantity of liquid cement in said trough must be such that only the lower face of said strip is rendered adhesive for properly building the Welt. This result is attained by engaging the pipes 24a, 24a into the trough 23a to the required heightso that they may act as overflow pipes. After being thus coated with liquid cement, the strip E enters the heating and drying chamber 30 in which it is guided over pulleys 95, 9B. When coming out of said chamber, the strip E reaches the pre-shaping device shown in Figure 9 and above-described.

Beyond the pre-shaping device shown in Figure 9, the three elements of which the welt will be formed already occupy correct positions relative to one another. Said elements (cord D, strip E and lap of threads F) then reach a shaping device as shown in Figure 10. This device comprises a bracket 97 carried by a cross slide 98 received between L-shaped vertical rail sections I00, I00 secured to the upright frame plate I5a of the machine. A clamping bar 98a is engaged by the stem of a bolt having a knurled head 99, said stem being screwed into the cross slide 90, whereby adjustment of the bolt 99 permits the cross slide 98 to be loosened or clamped at will and the bracket 91 to be adjusted to the desired height. The bracket 9! has a lower arcuate opening IOI provided with a pair of upwardly extending notches I02, I02 which are adapted to bend up the strip E.

When coming out of the shaping device shown in Figure 10, the elements D and F of the well; in the course of fabrlcationoccu'pytheir correct positions relative to each other and are accommodated in a channel formed by the bent strip. E.

, The elements thus relatively positioned then reach a further shaping device shown in Figure 11.

The shaping device shown in Figure 11 is supported from vertical rail sections 42a secured to the upright frame plate I5a by means of cross slides I03, I04, I05, clamping bars I03a, I04a, I05a and bolts having knurled heads I06, I01, I08. Adjustment heightwise is accomplished as above described with reference to Figure 6. The cross slide I03 carries a yoke rod I09 under which the partly made welt DE--F is caused to pass and be held down before reaching an opening IIO formed in a bracket III supported by a bracket I I2 carried by the cross slide I 05. The cross slide I04 carries a bracket II3 through which are adjustably secured a pair of hanging stems I I4, I I4 fitted at their lower ends with yoke rods H5, H5 adapted to hold down the upper edges of the crimped strip E.- By adjusting the position of the stems I I4, I I4 heightwise, the respective positions of the .yoke rods H5, H5 can also be adjusted for making a welt of the type shown in Figure 4 but wherein the wings of the wrapping strip E will be of unequal size. A further hanging stem IIG secured to the bracket II3 engages between the plies of the crimped strip E and holds down the cord D and the lap of agglutinated threads F as the welt passes through this shaping device. When going out of the apertured bracket I I I, the partly made welt passes through a slot I I! formed in a further bracket H8 and adapted to guide it. Both sides of the slot I I? are formed by jaws the mutual distance of which may be adjusted by means of a nut H9, through a worm gear of conventional shape (not visible in Figure 11) and fornirng no part of the invention.

Finally, the partly finished welt DE-F passes through a third shaping device shown in detail in Figure 12. The purpose of this shaping device is to give to the welt its definitive shape by still more closely bringing together its three elements which were previously caused to adhere as above stated. The device shown in Figure 12 comprises a bracket I20 carried by a cross slide I2I spanning a pair of upstanding rail sections 02a, 62a secured to the upright frame plate I 5a of the machine. A bolt having a knurled head I22 has its stem in engagement with said cross slide I2I and with a clamping bar I2 Ia having its ends bearing against the rail sections 62a, 62a. 0n the bracket I20 is carried a platen I23 having notches I24'through either the one or the other of which engages the upstanding shank of a clamping bolt I25. The platen I23 carries rollers I26 which press the bead G of the welt which lies on its side as it passes through this shaping device. The position of the platen I23 can be adjusted by loosening the bolt I25 and can be held invariable by tightening said bolt, which permits to vary the position where the pressing rollers I26 engage the welt bead G to suit the width of said welt. When leaving the platen I 23, the welt thus pressed together passes between a pair of pressing rollers I21, I28 having their axes journalled through the plate 13a secured to the upright frame plate I5a of the machine.

When leaving the pressing rollers I2], I20, the

. welt or flexible beading is ready for use. De-

pending on whichever side of the, machine to have been used, the welt thusfproduced is built as shown by Figure 1 or as shown by Figure 4. However, as above described, the manufacturing capacity of the machine is not limited to these two kinds of Welt.

Many similarswelts similarly made up of juxtaposed and assembled strips or bands may be produced in the machine.

It will be seen from the foregoing that the invention provides a machine requiring a minimum of labor and capable of automatically and continuously manufacturing different types of finishing welts. All the sequentially co-operating dragging, cement applying, juxtaposing and shaping means as above described are easily removable from the rail sections. or similar supports which carry them and adjustable along said supports. This permits to readily adjust the relative positions of said means and consequently to vary the respective'paths followed by the strip elements of which is to be made any welt in the course of fabrication. By varying said paths, the strip elements may be diversely brought together and juxtaposed. In other words, adjustment of said co-operating means makes it possible to easily appropriate the machine to the fabrication of many kinds of welt.

The constructional details of the machine may vary of course without departing from the scope of the subjoined claims.
